DETROIT — A judge ruled Friday that Mayor Kwame Kilpatrick be released from jail, pay a $50,000 cash bond, wear an electronic tether and not be allowed to travel.

Kilpatrick spent Thursday night in a one-man jail cell with no TV and a phone only for collect calls, the consequence of violating his bond in a criminal case that has dogged him for months.

But Wayne County Circuit Judge Thomas Jackson altered the ruling of a Detroit district court judge who ordered the mayor to jail a day earlier for violating the terms of his bond.

Jackson says District Judge Ronald Giles went too far in ordering the mayor to jail. He followed the prosecution's recommendation for setting the new bond, which defense attorney Jim Thomas called "piling on."

KILPATRICK CHARGED WITH FELONY ASSAULT

Michigan's attorney general says he's bringing assault charges against Detroit Mayor Kwame Kilpatrick after the mayor had a physical confrontation with a detective trying to deliver a subpoena.

The mayor faces two counts of assaulting or obstructing a police officer in the furtherance of their duties. Each felony count brings up to 2 years in prison or a fine of $2,000.

The mayor already faces perjury, official misconduct and obstruction of justice charges stemming from his testimony in a civil trial last year.

Attorney General Mike Cox announced the charges at a press conference in Detroit on Friday.

Kilpatrick was jailed Thursday for violating his bond, but was ordered to be released on appeal earlier Friday if he paid a $50,000 cash bond.

"In my almost 20 years, first as a prosecutor and now as an attorney general ... I cannot recall ever seeing let alone hearing of a situation where a police officer trying to serve a subpoena was assaulted," Attorney General Mike Cox said at a press conference to announce the charges.

Separately, the mayor and a former top aide are charged with perjury, misconduct and obstruction of justice, all tied to their testimony in a civil trial last year. At the heart of that case: steamy text messages contradicting their claim that they didn't have a romantic relationship.

To remain free while the case moves through court, Kilpatrick was required to notify authorities about business that required out-of-state travel.

He admitted violating that condition when he went to Windsor, Ontario -- minutes from Detroit -- on July 23 to discuss the sale of the city's portion of a tunnel connecting the U.S. and Canada. He didn't call prosecutors or 36th District Court.

"I'm asking for another chance," the mayor pleaded Thursday to Judge Ronald Giles.

The judge's response was swift and surprising: Jail for the leader of the country's 11th-largest city.

"I don't claim to have a good understanding of what your responsibilities are. ... But I have to look at how the (court) system is run and perceived by the public," Giles told the mayor.

Defense attorney Jim Thomas called Giles' ruling "extreme." Parkman said they would propose an electronic tether or some other conditions to get Kilpatrick out of the county jail.

Kilpatrick was transported to jail in a sheriff's van, photographed, given a green jumpsuit and placed in a one-man cell for high-profile people.

Although not in the general jail population, the mayor was being treated like any other prisoner -- "no better, no worse," Sheriff Warren Evans said. Evans told WDIV-TV Friday morning that Kilpatrick had an "uneventful night" in jail and would be permitted to dress in civilian clothes for Friday's court hearing before Jackson.

In May, the Detroit City Council asked Gov. Jennifer Granholm to invoke a little-used state law and remove Kilpatrick from office for misconduct. A hearing is scheduled for Sept. 3.
